CARLTON F. MARTIN, OF VOLGA, IOWA.

FLY-PRQTECTOR.

T 0 all whom it may concern:

Be it known that I, CARLTON F. MAnTin, a citizen of th United States, residing at Volga, in the county of Clayton and State of Iowa, have invented certain new and useful Im rovements in FlyProtectors; and I do dec are the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in fly protectors.

It has for its object more particularly to provide for the exclusion of flies, and the like, when opening and closin a screen door; and to provide for accomplishing this purpose in a simple and effective manner.

I/Vith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described and particularly pointed out in the appended claims.

In the accompanying drawing, illustrating the preferred embodiment of my invention, Figure 1 is a front elevation thereof, viewed from the outside; Fig. 2 is an inside view of the invention; Fig. 3 is a horizontal sectional view of said invention, with the door in full lines in closed position.

In carrying out my invention I suitably journal or support upon a screen door, on the outside, a carrier, 1, which may be of the general outline shown or other contour, and suitably equipped with agitating means, as flags or brushes, 2. The supporting bar, 1, of said screen door for said carrier is preferably suitably equipped, as by the use of opposite pieces of metal or plates, 3, in which is journaled an axis or shaft, 4, carrying tlie carrier and a pulley, 5, arranged upon the inside of the door. A line or cable, 6, is engaged with the pulley, 5, being once Wound around the same, and passed around or into engagement with a pulley, 7, suitably hung upon the door frame of the inside door, said line or cable also being passed through and connected to a staple or screw eye, 8, secured to said door frame a suitable distance away from said pulley. Said cable has its ends connected to a spring, 9, the tension of which has the effect of holding said line under stress, and also to serve in lieu of the usual spring for the screen door. If desired the aforesaid arrangement of parts may be duplicated by locating a carrier or agitator the same as that designated as 1, at a point Specification of Letters Patent.

Application filed June 15, 1908.

Patented Dec. 29, 1908.

Serial No. 438,61

marked 10 upon the bar 1, and extending the line or cable 6 so as to connect with the eye or staple, 8, as described, the remainder of the connections being the same as those above described.

Itwill be noted that as the screen door is opened, partially or full way, the line or cable, 6, will be so actuated as to cause frictional contact between the same and the pulley, 5, upon the shaft or axis, 4, of the agitator, or carrier, 1, and thus provide for revolving the latter and accordingly causing the brushes or agitators to clear the screen door of any flies or insects which may have alighted thereon, or which may attempt to enter the door opening, said action of said parts being also repeated, as is apparent, with the closing of the door, thus continually guarding the door-opening against the entrance of flies or insects during the opening or closing of the door. It will also be noted that by means of the aforesaid arrangement of parts, an exceedingly simple, inexpensive and effective contrivance for carrylng out the intended purpose of the invention is provided, and which is readily applied and 1 serves equally, as above noted, as a substitute for the ordinary screen door spring.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is:

1. A combined door closer and fly excluder comprising a door frame provided with a screw-eyelet, a spiral spring connected to the eyelet and extending above the same, a pulley secured to the door frame above the spring, a door hinged to the door frame, a rotatable carrier mounted on the door, and a cable connected at its lower end to the eyelet and arranged to engage the rotatable carrier and the pulley and connected at its upper end to the spring.

2. A combined door closer and fly excluder comprising a door frame provided with a screw-eyelet, a spiral spring extending above the eyelet and connected thereto, a pulley secured to the door frame above the spring, a door hinged to the door frame, a rotatable agitator mounted on the door, a plurality of flags mounted on the agitator, and a cable comprising a door frame provided with a a door, a second rotatable agitator mounted at its upper end to the spring and arranged l to engage the agitator on the pulley.

3. A combined door closer and fly eXcluder comprising a door frame provided with a screw eyelet, a spiral spring connected to the eyelet and extending vertically above said eyelet, a door hinged to the door frame, a plurality of rotatable carriers mounted on the door, a cable engaging one of the carriers and connected to the eyelet and the spring, and means for operating the remaining agitator.

4. A combined door closer and fly eXeluder screw-eyelet, a spiral spring extending above the eyelet and permanently connected thereto, a pulley secured to the door frame above the spring, a door hinged to the door frame, a rotatable agitator mounted on the on the door beneath the first mentionedf agitator, a plurality of springs vertically disposed on the door frame, cables connected to said springs and arranged to operate the agitators When the door is swung on its mnges.

5. A combined door closer and fly eXoluder comprising a door frame provided With a screw-eyelet, a door hinged to the do or frame, an agitator rotatably mounted on the door, a plurality of fiags mounted on the agitator, a cable arranged to engage the agitator and a vertically disposed spring connected to the cable.

in testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

CARLTON F. MARTIN.
